WINDsnInLD wrrnn.

I Application led January This invention appertainsv to novel cleaningdevices for cleaning wind shields of motor vehicles and the like and theprimary object ofn the invention is to provide novelv means forsupplying an anti-freezing fluid to the wiping 'elements for vpreventingthe freezing of snow and the like on the wlnd shield. y y

A further object of the invention is to provide a double wind' shieldcleanerv tor engaging the lopposite faces of t e wind shield and novelmeans for moving the wiping element in opposite directions, sd as toprevent binding thereof on the wind shielde A further object ot theinvention is the provision oi novel resilient arms for supporting thewiping element, whereby the same will be normally urged into propercontact with the wind shield.

A. further object of the invention is the provision of novel holders forretaining the wiping elements in place and novel means for pivotallyconnecting the holders to resilient arms, whereby the wiping elementwill be properly disposed relative to the wind shield irrespective otthe angle of the supporting bracket tor the arms relative to the windshield.

A further object of the invention is the provision ot novel hollowhandles carried. by the holders tor the wiping elemenusaid handlesforming reservoirs for the ole .1i or anti-freezing duid for permittingthe duid to be supplied to thewiping element by capillary action.

still further object of the invention--i`s.t ol provide an improved windshield wiper of the above character, which will be durable and eeient inuse, one that will be simple and easy to manufacture and one which c heplaced upon the market at a small cost.

With-these and other objects 'in view7 the invention consists in thenovel construction.

` arrangement and formation of parts, as will be hereinafter-morespecifically described, claimed and illustrated in the acoompandrawings, in which drawings: v Figure l is a rear elevation oftheimproved wiper, f.

Referring to the drawings in detail,

wherein similar reference characters designate corresponding partsthroughout the several views the letter` A generally indicates theimproved wind shield cleaner and B a wind shield with which the same isassociated,

The wind shield B forms no part ot the present invention and has simplybeen shown to illustrate the use of the improved cleanerl and the windshield includes the usual glass anel l0 and trame ll therefore whicheinu odies the apporti-ame bar l2.

' The improved wind shield cleaner l cornprises a pair ot resilientsupporting and operating arms l5 and 16 which are adapted tothe disposed`on the opposite sides oi"- the glass panel of the wind shield to becleaned.=

The lower terminals of the resilient arms l5 I longitudinal edges of thewalls 21 are provided with flared lips 23 which form means forfacilitating the placing of the cleaning or wiping element 19 in thebody between the walls. ln view of' the fact that the body is formed ofresilient material the arallel walls 21 serve as means for gripping thecleaning or wiping element so as tok firmly hold the same in place.rllhe wiping or cleaning element 19 is preferably formed from felt andis provided at its lower end with an angularly extending ortion 24 whichforms a wick, as will be ereinafter more fully described, for permittingthe anti-freezin liquid to be supplied constantly to the c eaning orwiping element. As shown the lower end of each holder is provided withthe outwardly extending integral nipple 25 which is preferably providedwith external threads for receiving the hollow hand grip 26 which formsa reservoir for the cleaning andl anti-freezing fluid. lit is to benoted that the wick portion 24 ot the cleaning or wiping element 19extends within the said handle or reservoir. By this construction it canbe seen that the cleaning or non-freezing fluid will be fed by capillaryattraction to the said cleaning or wiping element of the wind shieldcleaner.

As heretobefore stated one ot the objects of the invention is to providenovel means for synchronously operating the arms, in such a manner thatthe arms will move in opposite direction, so as to insure propercleaning of the wind shield and to prevent binding action of the wipinglor cleaning elements 19 on the opposite faces of the lass panel. lln'order to efficiently bring a out this result, a gear casing 30 isprovided which supports the l op ositely extending stub shafts 31 and32. 'll ese stub shafts 31 and 32 have keyed or otherwise securedthereto pinions 33 which are disposed in intermeshing engagement withone another. 'llhe stub shaft 32 has adjustably secured thereto in anyydesired way for rotation therewith the arm 16, while the shaft 31 hasrigidly and adjustably secured to the shaft 31 for rotation therewiththe arm 15.. As shown the outer terminals of 'the shafts are preferablyreduced and threaded for the reception of jam nuts 34 which are adaptedto engage the arms 15- and 16 -to clamp the same on the said shafts.`rllhe gear casing 30 is provided with a suitable removable cover late 35as shown in Figure 2 of the rawing.

By this construction it can be seen that when either one of the handlesV26 of the cleaner is grasped and swung in an arc, that both of the arms15 and, 16 will be synchronously operated and moved in oppositedirection which will bring about the desired results. 1t is to beunderstood, that while l have described the device as being manuallymonaca operated, the same can be automatically operated by an electricor suction operated motor.

l also provide novel means for clampingl the improved wind shieldcleaner in place and as shown the gear casing 3() carries rearwardlyextending bolts 36 which are fitted within slots 37 in a clamping plate38. This clamping plate 38 has its lower end shaped to conform to theconfiguration of the uper bar 12 of the frame 11 of the wind shield andthis plate is adapted to be adjusted toward and away from the gearcasing 30 and in a vertical plane so as to permit the same to readilygrip different sized wind shield frames. The clamping plate 38 is heldin proper clamping relation by the use of suitable nuts 39 threaded uponthe bolts 36. It is to be noted that the casing 30 is disposed on oneside of the wind shield frame while the clamping plate is disposed onthe other side vot the frame and that the gear casing and the clampingplate form jaws for engaging the opposite faces of the wind shieldframe. llt might be also well to point out that the bolts 36 form themeans or retaining the cover 35 in position and that suitable nuts 40are threaded upon the bolts into engagement with said cover.

Other means can be utilized for connect ing therimproved device in placeand in` lFigurel ll have shown means for connecting the same to anautomobile of the closedI type. ln this form the casing 30 is lower, sothat the same will not project above the wind shield and the fasteningbolt 36 'and the shaft 31 were extended directly through the upper'fastening bar 12 of the wind shield as clearly shown in this figure.

'While ll have stated that the hollow handles or reservoirs 26 areadapted to receive a non-freezing fluid, so as to prevent freezing ofrain and the like on the wind shield, it 1s to be understood that thereservoir can be filled in summer time with a fluid to prel vent theadhering of rain and moisture on the wind shield.

llt is to be noted, that owing to the means for pivotally connecting theholders 18 to the arms, that the wiping elements will correctly engagethe wind shield irrespective of whether the clamp is disposed on adirect vertical plane or not. l

From the foregoing description, it' can be seen that 1 have rovided aneflicient wind shield'cleaner whlch will operate in a novel manner andserve as means for supplyinga duid to the opposite face` of the windshield at all times to prevent the freezing and adhering of snow and thelike thereon.

Changes as to details may be made withoutdeparting from the spirit orthe scope of this invention.

What ll claim as new is:

1. A windshield cleaner comprising a gear casing, clamping means forconnecting the gear casing to the windshield, oppositely extending stubshafts rotatably carried by the casing having .their opposite endsprojecting outward. from the opposite sides of the casing,depending-arms secured to the extended ends ofthe stub shafts forrotation. therewith, intermeshing pinions keyed to the stub shafts,holders secured to the lower ends of the arms, and windshield wipingand' cleaning elements carried by the holders for engaging the oppositefaces of the Windshield. V v

2. a windshield cleaning device, a

holder, a wiping element frictionally mount- 15 ed in the holder forengaging the windshield to be cleaned, an angular-ly' extending nippleformed on the lower end of the holder, a hollow handle detachablyconnected with the nipple'forming a reservoir for a Huid, and anextension formed on the lower end of thev wiping element disposed in thehandle for feeding the liquid contained therein to the wiping element bycapillary attraction.
